I have.
[0023]
The electric wire side connector 50 is assembled as follows.
First, the shielded electric wire 40 is inserted into the center hole 61 of the bracket 60 from behind, and the front end of the shield layer 43 is connected to the bracket 60 via the underlay pipe 64 and the caulking ring 65. Next, a rubber sealing member 58 is externally fitted to the core 42 of the shielded electric wire 40 from the front, and the sealing member 58 is brought into contact with the flange portion 64F of the underlaying pipe 64 and pressed against the front surface of the bracket 60. The seal member 58 is restricted from floating around the outer periphery of the core 42 by friction. Thereafter, the wire crimping portion 74 of the wire side terminal 70 is fixed to the front end of the conductor 41 of the shielded wire 40. As described above, the wire-side terminal 70 is connected to the front end of the shielded wire 40.
[0024]
Next, the shielded wire 40, the bracket 60 and the wire-side terminal 70 are assembled to the wire-side housing 51. When assembling, the wire-side terminal 70 is inserted into the cavity 52 from behind. The wire side terminal 70 inserted deeply to the proper position is stopped beforehand by bringing the device connecting portion 71 into contact with the front wall of the cavity 52, and is unplugged by the lance 53 being locked in the lance hole 73. Be stopped. In addition, the seal member 58 externally fitted to the core 42 is in close contact with the inner periphery of the rear end portion of the cavity 52, whereby the space between the inner periphery of the cavity 52 and the outer periphery of the core 42 is sealed in a water-restricted state.
[0025]
As the electric wire side terminal 70 is inserted into the cavity 52, the bracket 60 approaches the electric wire side housing 51 from the rear, and the elastic locking pieces of the electric wire side housing 51 are respectively inserted into the locking holes 63 of the bracket 60. 54 and the protection piece 55 are penetrated from the front, the locking claw 54A at the rear end of the elastic locking piece 54 is locked from the rear with respect to the outer peripheral side edge of the locking hole 63, and the elastic locking piece 54 By the engagement with the engagement hole 63, the rearward separation of the bracket 60 from the electric wire side housing 51 is regulated. In this locked state, the front surface of the bracket 60 abuts against the rear end surface of the electric wire side housing 51 from behind, thereby restricting the bracket 60 from being relatively displaced forward with respect to the electric wire side housing 51. That is, the bracket 60 is locked in an integrated state with the electric wire side housing 51. In this temporarily locked state, the seal member 58 is sandwiched between the flange portion 64F and the stopper 52S of the cavity 52 back and forth, and the elastic repulsive force of the seal member 58 pushes the flange portion 64F against the bracket 60, and The pipe 64 and the bracket 60 are surely in contact with each other.
[0026]
When the electric wire side connector 50 is assembled, the three shielded electric wires 40 are housed in the corrugated tube 45 in a state of being bundled in a bale stack. A split groove (not shown) is formed in the corrugated tube 45 along its length direction. By expanding the split groove, the shielded electric wire 40 can be housed inside. Further, the rubber boots 46 are put on the ends of the three shielded wires 40. At this time, the rubber boots 46 allow the three wire-side terminals 70 to pass therethrough while elastically expanding the small-diameter outer fitting portions 49 at the rear ends. What should I do? By externally fitting the small-diameter outer fitting portion 49 of the rubber boot 46 to the front end of the corrugated tube 45, the corrugated tube 45 and the rubber boot 46 are integrated, and surround the shielded electric wire 40 over its entire length.
[0027]
The wire-side housing 51 of the wire-side connector 50 is fitted into each of the mounting holes 12 of the shield case 11. Inside the mounting hole 12, the device-side housing 21 is waiting in advance, and when the wire-side housing 51 is inserted sufficiently deeply until the bracket 60 comes into contact with the outer surface of the shield case 11, the front end portion of the device-side housing 21 21 is fitted into the fitting recess 23F, and the tab 28 enters the device connecting portion 71 of the electric wire side terminal 70 and makes elastic contact with the elastic contact piece 72, so that the two terminals 26 and 70 are electrically connected. Is done.
[0028]
When the electric wire side housing 51 is fitted in the mounting hole 12, the bolt hole 62 of the bracket 60 is aligned with the female screw hole of the shield case 11, and the bolt 69 penetrating the bolt hole 62 is screwed into the female screw hole. By tightening, the bracket 60 is fixed in a state where it is conductively connected to the outer wall surface of the shield case 11, and the shield layer 43 of the shielded wire 40 is conductively connected to the shield case 11. . Further, since the bracket 60 is in contact with the rear end surface of the electric wire side housing 51, the electric wire side housing 51 is restricted from coming out (to the rear) from the mounting hole 12.
[0029]
Further, the large-diameter outer fitting portion 47 at the front end of the rubber boot 46 is externally fitted to the bulging portion 13 of the shield case 11, and the lip portion 48 is brought into elastic contact with the outer periphery thereof. Thereby, the connection between the bracket 60 and the shield layer 43 is in a waterproof state. The space between the inner periphery of the mounting hole 12 and the outer periphery of the electric wire side housing 51 is waterproofed by a seal member 57.
As described above, in the present embodiment, although the sheath for protecting the shield layer 43 is not provided on the shielded electric wire 40, the entire length of the shielded electric wire 40 (at least the exposed portion of the shield layer 43 of the shielded electric wire 40 is not exposed). Region) is accommodated in the corrugated tube 45 and the rubber boot 46 to protect it. As described above, according to the present embodiment, it is possible to eliminate the sheath from the shielded electric wire 40. Therefore, the shielded electric wire 40 can be reduced in diameter and weight by the amount of the sheath, and the bending rigidity can be reduced. Has been realized.
[0030]
Further, since the wire-side terminal 70 is held by the wire-side housing 51 and the wire-side housing 51 is fitted into the mounting hole 12 of the shield case 11, the wire-side terminal 70 is held against the shield case 11 and the device-side terminal 26. Positioning can be performed in the radial direction and the front-back direction, thereby improving workability in connecting the two terminals 26 and 70 to each other.
In addition, the shield layer 43 is connected to the bracket 60 outside the wire-side housing 51 and the bracket 60 is attached to the shield case 11, and the front end of the core 42 is inserted into the wire-side housing 51. A seal member 58 is provided between the core and the core. In other words, the shield processing structure (the connection structure between the shield layer 43 and the bracket 60) at the end of the shielded wire 40 and the waterproof structure between the shielded wire 40 and the wire-side housing 51 (between the core 42 and the wire-side housing 51) (A structure in which a seal member 58 is provided) is divided into the outside and the inside of the electric wire side housing 51, so that the simplification of these structures is realized.
[0031]
Further, since the elastic locking piece 54 and the locking hole 63 are provided as temporary locking means for temporarily locking the bracket 60 and the electric wire side housing 51, the bracket 60 and the electric wire side housing 51 are integrated. And the workability in assembling to the shield case 11 is improved.
When the bracket 60 and the wire-side housing 51 are assembled to the shield case 11, the bracket 60 is configured to contact the wire-side housing 51 from the rear in the mounting direction, and the bracket 60 prevents the wire-side housing 51 from coming off. It also serves as a means. This eliminates the need for a means for retaining the electric wire side housing 51, thereby simplifying the structure.
[0032]
The device-side terminal 26 is held by the device-side housing 21, the device-side housing 21 is provided in the mounting hole 12, and the wire-side housing 51 is fitted into the device-side housing 21 in the mounting hole 12. Since the side terminal 26 and the electric wire side terminal 70 are connected, the connection between the device side terminal 26 and the electric wire side terminal 70 can be performed only by fitting the device side housing 21 and the electric wire side housing 51. Has become. Therefore, there is no need to directly connect the terminals 26 and 70 to each other by a troublesome bolting operation, and the workability is excellent. Further, when the terminals are connected by bolting, it is necessary to cover the connection between the terminals with a cover for protection after the bolting. According to the present embodiment, both terminals 26 and 70 are connected. Is housed inside the mounting hole 12, so that there is no need to cover it for protection.
